An important feature of the proposed detector method is that both approaches can be combined with existing beamforming techniques.
This feature ensures that for some applications the performance can be even further improved.
This is also shown in Figure REF , in both diagrams the dashed lines denote the beamformer and the solid line above the beamformer box is omitted when the beamformer is used.
Here the F-SVAD and A-SVAD combined with the beamformer becomes FB-SVAD and AB-SVAD, respectively.
For this paper, a delay and sum (DS) beamformer [1]} is chosen to show the performance increase obtained by including additional beamforming.
Other beamforming methods such as minimum variance distortionless response, linearly constrained minimum variance and multi-channel Wiener filter may substitute the DS beamformer to obtain even better results [2]}.
